Amalgam Attribute Based Encryption Scheme over the Cloud Data for Secure Access in the Hybrid Cloud
Raj Priyadarshini · 2014
In the emergence of cloud computing, data owners are aggravated to outsource their complex data management system from local site to commercial cloud for great flexibility and economic saving. But for protecting data privacy, sensitive data has to be encrypted before outsourcing to commercial public cloud. Encrypted cloud data search system remains a very challenging task because of inherent security and privacy obstacles. There are so many security issues over the hybrid cloud during migration of data from one site to public cloud and also we cannot handle group of receivers in case of SKE. For secure communication and also handle dynamic attributes with continuous values, we need a new technique called as Amalgam attribute based encryption techniques. It is amalgam, as it combines the cipher text –policy attribute-based encryption (CPABE) with location-based encryption (LBE) on the level of symmetric keys in the hybrid cloud.
